For some reason the last two weeks seems to have really brought out all the terrible drivers here. In a state where 5-10mph over is considered the "real" speed limit by practice (in that police won't pull you over for that, and traffic flow on any given road is typically that pace), it is absolutely infuriating to get stuck behind someone going 10mph under. Sometimes it is worse.
No turn signals is a huge pet peeve of mine. Blargh. But what bothers me even more is when people start slowing down, slowing down, slowing down, then when they are going about 20mph, only THEN do they turn on their turn signal. You signal, THEN begin to slow. I nearly hit someone's driver's side door once because of that - they were already driving extremely erratically, slowing down and speeding up (and no, I wasn't tailgating - I don't ever do that, it's another pet peeve), never more than 45mph, so once I got to a passing zone I started to go around - lucky for them I caught the turn signal in time.
Tailgating is another huge pet peeve of mine. No, poop-for-brains, riding three inches off my bumper isn't going to make me speed up. It makes me slow down. I just set cruise control and start tapping the "set" button to drop my speed 1mph at a time. I usually have to drop down to about 40-45mph (from 60-62mph) before they get the message. And then a mile later down the road, after backing way off, they'll finally get the message. I had someone riding my bumper so close once at night (when I was driving, again, about 60mph) that I didn't know they were tailgating for about three miles. I thought they'd turned off, but no, they were just so **** close the back of my truck was blocking their headlights.
I've done "brake checks" before too when people ride that close.
